Electronically controlled valve and systems containing same

摘要

Disclosed herein is a controlled valve. The valve includes a valve body, a sleeve, a spool, and a valve actuator assembly. The valve body includes a cavity and a first chamber. The sleeve is between the cavity and the first chamber. The sleeve includes an inner bore and at least one opening. The inner bore extends from a first end to a second end of the sleeve. The at least one opening extends through the second end of the sleeve. A portion of the inner bore forms a second chamber. The spool is movably disposed within the inner bore. The valve actuator assembly is connected to the spool. The first chamber is in fluid communication with the second chamber through the at least one opening. The spool is configured to be movable over at least a portion of the at least one opening to regulate fluid flow therethrough.

1. A controlled valve comprising:
a valve body comprising a top end, a bottom end, and a receiving area proximate the bottom end; a sleeve between the top end and the bottom end, wherein the sleeve comprises an inner bore and at least one opening, wherein the inner bore extends from a first end of the sleeve to a second end of the sleeve, and wherein the at least one opening extends through the second end of the sleeve; a valve body base comprising a first end and a second opposite end, wherein the sleeve is attached to the first end of the valve body base, and wherein the second end of the valve body base is configured to receive a first conduit; a spool movably disposed within the inner bore of the sleeve, wherein the spool is configured to be movable in a first direction; and an electromagnetic valve actuator assembly attached to the spool, wherein the electromagnetic valve actuator assembly is inside the valve body and proximate the top end of the valve body; wherein the valve is configured to receive a second conduit at the receiving area, wherein the valve is configured to provide for fluid communication through the at least one opening, wherein the spool is configured to be movable over at least a portion of the at least one opening to regulate fluid flow therethrough, and wherein the valve is configured to provide a fluid flow at the bottom end of the valve body that is substantially parallel to the first direction.
